Cost-based query optimizer foundation lands, plus a runtime hook for the storage layer to dispatch index lookups.
     Optimizer: new IContainerStatistics abstraction + CostModel (statistics-driven cost/cardinality for the physical operator surface).
     Optimizer: new IIndexCatalog + IndexAwareQueryPlanOptimizer — recognizes /element[@attr=literal] shapes and emits IndexLookupOperator when an index covers the path.
     Optimizer: FlworJoinReorderer topologically sorts multi-binding for clauses by cost, respecting data dependencies.
     Execution: IndexLookupOperator now falls back to QueryExecutionContext.IndexLookupResolver when its inline LookupAsync delegate is unset. New IIndexLookupResolver interface lets a host attach per-query dispatch without rewriting compiled plans.
     Fix: fn:serialize with output:indent and method=json now emits pretty-printed JSON (regression test added).
